  • Page 24 Figure 2-7. Cabling to a LAN NOTE: If there is no Ethernet cable attached to the MP/16 when you power it on, the MP/16 defaults to the AUI port. If you later decide to connect to the UTP port, you must reset the MP/16 by powering it off.

  • Page 37: Chapter 3 Using Total Control Mibs

    Marshall T. Rose. Total Control MIBs and the U.S. Robotics Enterprise The Total Control MP/16 uses a subset of the Total Control MIBs. They are identical to compatible revisions of MIBs used with other U.S. Robotics enterprise equipment. The complete set of Total Control MIBs are comprised of the standard MIBII, the DS1 MIB, and a number of enterprise-specific MIBs.

    Issuance of this SET operation also internally sets the read-only ReqId object to the value of the request-id field in the SNMP SET PDU. If the MP/16 is able to handle the command, the read-only Result object is set to inProgress(3) and activation of the command begins.

    Although this group has been deprecated (will become obsolete in the next MIB version), the MP/16 implements it for MIBI compatibility as defined in MIBII.

    The term card is used to describe a managed module in the MP/16, while slot is used to describe its location.

  • Page 49 the device. Because the NMC needs to support the TFTP protocol and, as a result, the entire IP stack, a large portion of the NMC’s operational code remains running. Moreover, the SDL functionality is built int o the NMC’s operational code. In this way, SNMP-initiated SDLs need not transfer an .SDL file when NMC SDL is triggered.

  • Page 50: The Nmc Mib

    The NMC MIB Although the MP/16 management module can not be accurately termed an “NMC,” it uses the Total Control NMC MIB, as it behaves identically in respect to its implementation of applicable NMC MIB variables. To remain consistent with NMC MIB table entries and extensions, the MP/16 management module should be thought of as the NMC when applying MIBs to the MP/16.
  • Page 51 The NMC's Real-Time Clock Before setting the NMC's real time clock, it is important to tell the NMC what time zone it is in to aid in converting times between local time and Greenwich Mean Time (GMT). This is done by setting nmcTimezone to the appropriate value.

NOTE: The values for nmcCfgAtString and nmcCfgWanDialOutPhoneNum can be modified to connect the WAN port to other devices, such as an X.25 PAD. NMC Status Information Most of the objects in the nmcStat group are self-explanatory, with the exception of the NMC test result bitmaps.

If all power up tests pass, the NMC Run/Fail LED remains solid green.
  • Page 55 NMC Commands Configuration-related Commands Before discussing each of the configuration-related NMC commands, there are a number of items that need to be addressed. First is the issue of NVRAM. Each NAC has its own NVRAM. In addition, the NMC has its own NVRAM. The two are completely independent.

  • Page 57 Command Description restoreFromNvram(4) With the exception of the nmcUiCfg group, this command restores all configurable NMC parameters to the value last saved to the NMC's NVRAM. In addition, an attempt is made to restore the cache for each slot to the values that were last saved to the NMC's NVRAM.

  • Page 58: Configuration Parameters

    Both the public (read-only view) and private (read-write view) community strings take effect immediately, but if the NMC is reset without issuing a saveUiParamsToEEPROM command, they will revert to the values last saved to EEPROM. 3-22 Using Total Control MIBs...
  • Page 59 NMC Authorized Access List By default, the NMC authorized access table is empty. In this state, there is no restriction on which management stations may manage the chassis. Once a row is added to the authorized access table, only management stations whose IP addresses pass the authorization validation against the table are permitted access to the NMC for the purposes of network management.

  • Page 61: Event Log

    The NMC client removes an event record from its input queue, formats it properly for the RADIUS server, sends it, and waits for the reply before starting on the next event record. If the NMC client is unable to communicate with a RADIUS server, the NMC client discards the event records.
